The female bus driver who accused Matthew Fox of assaulting her in August (11) has filed papers demanding the actor's countersuit against her is dismissed.

The Lost star attempted to board a party bus in Ohio when he was confronted by driver Heather Bormann because his name was not on the private guestlist.

A scuffle ensued and Fox was accused of hitting Bormann, while the female driver allegedly punched the actor in the face. Matthew Fox was detained by police but not formally arrested.

Just weeks later, Bormann sued the actor, accusing him of assault, battery and intentional infliction of emotional distress, but Fox hit back with a countersuit claiming the driver provoked him and subsequently subjected him to "public hatred, contempt, ridicule and shame" due to the media fallout.

Bormann is refusing to accept Fox's lawsuit, branding his claims "baseless, impertinent, scandalous, and frivolous", according to E! Online.

She wants Matthew Fox's suit dismissed and is seeking $25,000 from the star.
